Sealed Thin-Section Bearings (Deep Groove Ball Structure), Type C: Engineered for Low Torque, Weight Efficiency, and Compactness

Type C Sealed Thin-Section Bearings, featuring a deep groove ball structure, are engineered to deliver low torque characteristics while enabling substantial weight and space savings. Widely adopted in critical applications such as radar systems, armaments, and precision instruments, these bearings balance performance with the space-constrained requirements.

Standard configurations utilize double sealing to enhance protection; however, single-side sealing variants are available to accommodate specific operational environments. Seals are fabricated from nitrile rubber (NBR), ensuring robust resistance to contaminants and extended service life in demanding conditions.
